The problem is due to rtl8192ce and rtl8192cu sharing routines, and having different layouts of struct rtl_pci_priv, which is used by rtl8192ce, and struct rtl_usb_priv, which is used by rtl8192cu. The problem was resolved by placing the struct bt_coexist_info at the head of each of those private areas.
